Title: full flash read results in End Address is not the end of flash memory Post by: gumbotrom on July 09, 2026, 12:03:36 PM Hey I have a 2001 golf gti 1.8t awd code, the ecu is 06A 906 032 CL so I'm using the 400bb layout as its the narrowband ecu and has the 512kb file, i also put in a 06A 906 032 C with the same results but I'm pretty sure that one would have a read/write lock maybe cause it has a tune. i think its good to note I'm using a ch340 kkl cable but did try a ft232rl k+dcan cable that my buddy had and had the same result I'm gonna try a proper kkl one soon but for now i thought I'd ask if when i get this message i should just wait because I'm guessing it could be sorta like VAG EEPROM programmer on immo2 where it has to search through every hex code but isn't visibly doing it but i just see online i should just cancel operation when it happens. I got a similar message when i perform a write too, i know i shouldn't write before i read the og file but it wasn't working so i tried to see what happens. The full thread received when i perform a full flash read is:
Reading ECU flash memory. Negotiating communication timings. Successfully changed to new communication timings. Requesting security access. Security access granted. Negotiating communication timings. Successfully changed to new communication timings. Requesting security access. Security access granted. Validating flash memory starts at 0x00800000 and ends at 0x00880000. End address is not the end of flash memory. should i just sit there for awhile and it if anything happens.

I don’t know anything about the background of the vehicle but maybe try also pulling the ECU and using flashdock.exe (a modern galletto alternative made by @nameless_) and you can read the ECU in boot mode. Nefmoto supports boot mode too hope you find success

It should be in
Code: AppData\Roaming\Nefarious Motorsports\NefMoto VW Audi ME7 Flasher Logger\NefMoto VW Audi ME7 Flasher LoggerLog.txt The file in the dialog when you start to read is only used in fast read. it is ignored in full read. the save file option should come up when full read is done.
